Air floatation sewage treatment device based on ultramicro nano bubbles

Abstract

The invention provides an air flotation sewage treatment device based on ultra-micro nano bubbles, and relates to the technical field of sewage treatment.The air flotation sewage treatment device based on the ultra-micro nano bubbles comprises a cylindrical air flotation tank, an air flotation machine is arranged in the air flotation tank, a transverse plate is arranged over the air flotation tank, and the transverse plate is connected with the air flotation tank. A driving mechanism for driving the air floatation tank to rotate in the circumferential direction is arranged on one side of the transverse plate, a push plate located at the top of the air floatation tank is arranged at the bottom of the transverse plate, and the bottom of the push plate extends into the air floatation tank; sewage is continuously added into the air flotation tank, the sewage gradually overflows from the top of the air flotation tank to enter the overflow cavity, then the sewage is treated through the air flotation machine, impurities in the sewage float out of the interior of the sewage to the position above the liquid level and enter the interior of the overflow cavity along with the overflowed sewage, and a transverse plate is driven by a driving mechanism to rotate, so that the sewage is discharged out of the overflow cavity. The push plate rotates at the top of the air floatation tank along with the rotating transverse plate.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an air flotation sewage treatment device based on ultrafine nano bubbles. Background technique [0002] The air flotation machine is a dissolved air system that produces a large number of fine air bubbles in the water, so that the air adheres to the suspended particles in the form of highly dispersed fine air bubbles, resulting in a state where the density is lower than that of water. -Water treatment equipment for liquid separation, air flotation machines are divided into super-efficient shallow air flotation machines, vortex concave air flotation machines, and advection air flotation machines, which are used in water supply, industrial wastewater and urban sewage treatment. The advantage is that its solid-liquid separation equipment has the characteristics of less investment, extremely small footprint, high degree of automation, and convenient operation and management....
